Costate var., plate VI. fig. 3. 
In this form the markings are more uniform, varying only in size. 
Becoming more robust, it develops in the direction of M. licornis. 
Agglutinate var., plate VI. fig. 4. 
Closely resembles M. fusca. The surface is beset with minute 
glittering scales and very small grains of sand attached to, but not 
enclosed within, the porcellanous shell-substance. 
All the foregoing varieties are common and widespread in both 
areas. 
Treating of the Miliolinse with surface ornaments, Brady writes, 
“ A few varieties may be disposed of by referring them to the smooth- 
shelled species having the same general contour.” * Holding this 
opinion, Brady might with advantage have carried the process a little 
further than he did. Taking, for example, the species M. tricarinata 
and its varieties, the terms striate variety and reticulate variety are 
self-explanatory, whilst Brady’s names for the same forms, M. Ter- 
quemiana and M. Bertheliniana, give no idea of their character and 
affinities. 
In these Malay gatherings, so numerous are the transition forms 
that much light is thrown by them on the affinities of the Miliolinse , 
although unfortunately not sufficient to enable us to link together the 
whole of the species. 
Miliolina transversestriata Brady, plate VI. fig. 5. 
Miliolina transversestriata Brady, 1881, Quart. Journ. Micr. Sci., 
vol. xxi. n.s. p. 45. M. transversestriata Brady, 1884, Cliall. Kept., 
p. 177, pi. iv. fig. 6. 
Hitherto recorded only from the ‘ Challenger ’ dredgings, and in 
them in but two localities, Kaine Island, Torres Strait, 155 fathoms, 
and in harbour-mud from Port Louis, Mauritius. 
It is rather rare, but occurs at Stations in both Areas. 
Aperture edentate. 
Miliolina Durrandii sp. n., plate VI. fig 4. 7-10. 
Test broadly elliptical, much depressed, chambers few, periphery 
acute or carinate, sutures slightly excavated, aperture large, elliptical 
or fusiform, surrounded by a thickened lip, edentate. Length 0*77 
to 0*99 mm. 
This is one of an interesting group in which the aperture is a 
large elliptical or fusiform opening without teeth. As in M. rotunda , 
the Biloculine form (figs. 8-10) is the larger. The costae represented 
in fig. 7 are confined to the anterior portion of the test, and are
